I have a set of bi-xenon projectors in my w126 euro headlights. My setup came from a 2002 audi a6. I currently don't have the high beams wired anymore because i couldn't get them wired the way I wanted. Anyway having the glass fluted lense is definently a disadvantage when it comes to hids. It destroys the cut off step ___/, but I still have a sharp cut off that looks like this ____. Word to the wise though, if you are going to retro projectors in your headlights, PAY somebody to do it. The former hidforum (R.I.P.) and the current hidplanet are great sources of information on xenon lights. You can learn so much. So visit hidplanet to learn more about hids than you may have ever wanted to know.
